DYWIDAG Threadbar® Tie Rod Applications Tie Rods produced from DYWIDAG THREADBAR® may be used for a variety of marine applications. Construction of marine bulkheads for various docking facilities have, for many years, benefited from the use of DYWIDAG Tie Rods. Facilities such as barge and ship docks as well as offshore platforms have found the system to be a cost effective alternative to large d iameter A36 Tie Rods with upset threads. Tie Rods produced from DYWIDAG conomical THREADBAR® offer various e and technical advantages: n Easy handling due to the coarse
thread over the entire length n Up to almost 50% less weight than
A36 bars. n No threadability or assembly
roblems resulting from damaged p or dirty threads, because of the rugged hot rolled coarse DYWIDAG threadform. n DYWIDAG Tie Rods can be ordered slightly longer than necessary to accommodate misalignments on sheet piling. They can easily be cut to the desired length eliminating need to cut and re-weld upset rods to accommodate length changes.

DYWIDAG Tie Rod Corrosion Protection An important element in the long term durability of a Tie Rod system is corrosion protection. DSI offers various corrosion protection systems to meet on site conditions and degree of exposure. Possible solutions are: n The well known DYWIDAG Double
orrosion Protection (D) System. C Ideal for the most aggressive environments n Hot dip galvanizing in accordance
with ASTM A153 n Fusion bonded epoxy coating
per ASTM A775 or ATSM A934
n Coal tar epoxy n Petroleum wax tape wrapping n Polyken 980/955 tape coating system
D threadbar® - exposed section
D threadbar® - cross section area

Short Tie Rod Connection Short bolts are needed to connect a standard sheet pile wall or a modular sheet pile wall to a load distributing double channel beam. This can be done with DYWIDAG THREADBAR®.
DYWIDAG Tie Rods can also be prestressed, to align sheet pile walls.
n Wide range of accessories available
Features and advantages:
n Available with double corrosion
n Continuous coarse DYWIDAG thread
The required length of the bar depends on the height of the sheet pile profile, the width of the beam, the plate thickness and the nut length.
protection system
n Approved by many construction
authorities worldwide
n Can be cut to any length n Conformance to ASTM A615 n Weldable accessories
